DV never been changed

[gigolo456]

Others will prob comment on the technical side of what the DV is actually for, but mine is also a 2005 GTi. I had my DV changed in June to a Rev G. Im glad I did cause the stock Rev C was indeed split! Now, I had a lot of mods done around then, and at same time, so cant comment as to what benefit that change alone mite bring, but for the sake of £37, id do it out of precaution alone! Id even go as far as to suggest that if yr current DV is split, this mite actually be the most important mod out there, if one could call it a mod!?

Call me stupid, but what is a diverter valve?    Keep hearing people on here talking about them, but I have no idea what it is. I have had my 05 GTI (unmodded) from new and never had anything done to mine. What difference do the revision ones make? Are they simply more durable or do they actually have some performance improvement?

The diverter valve cuts off the flow of boost to your engine when you lift off the throttle, and recirculates the air back round the system to reduce turbo lag when you plant your foot again. Its a small part that sits on the side of the turbo.

The newer revisions are more durable than their predecessors (early ones are very prone to splitting and leaking boost), no performance improvement with the newer ones

Good explanation, thanks! 
Might get mine looked at when i'm in for a service.

Chances are, you ask a dealer to check yr DV, they will respond with, 'What's that?', lol!!

Haha you're probably right. I use my local independant specialist these days, so they're more likely to know what they're doing.

Change yr pcv valve and cam follower, if not already!? Let the slippery slope begin!!! ;-)

[homesqueeze]

Don't even know what that means!

For what it's worth, it's dead easy to change if you've got a standard undertray. If the car was parked with the right handside on a kerb and you're not a portly squire, you could easily crawl under, reach up the back of the engine and change. Can be done in a matter of minutes.

Have you tried it? I had mine on ramps and it took about 45 minutes. Perhaps in mitigation it was because it was my first time (fnarr). I found the working room limited and I was also working blind to remove/replace the top bolt.

Yep - it's a doddle. Did it on the driveway just by reaching up the back of the engine, whilst the OSF wheel was on a block of wood.

Ahh so you weren't working blind because you could see the bolts through the wheel arch? Or am I getting this completely wrong?

On my back under the car. You can see / feel your way around sufficiently.

Changed my dv yesterday to the Revision D one. The old one was in mint condition with no tears of splits.... and thats after 72k

Think this is the guide to fitting? no part numbers there though

What Rev was your old one.. Part number is on the side?
